sendmail.cf DS line

[jerry1]

Can someone tell me what the difference is
for relay DS:

DSmailhost.$?m.$m

and

DSmailhost.$m

They both work but what does $?m do?

Usually, DS is set to just:

DSmailhost

$m forces local domain?

Is this what you are trying to do:

# Direct SMTP connection with local domain: #
# #
# To deliver mail destined for hosts within the local domain directly, #
# while sending all other mail to the "Smart Relay" listed above, you #
# will need to uncomment the line in ruleset 0 following the comment: #
# #
# # See if we are supposed to deliver to hosts in the local domain #
# #
# Also ensure the $m macro gets defined. It gets defined internally #
# from $j macro. You can check if it is set by doing the following:
